I had recently moved to 91 octane to get rid of pinging, I also cleaned that little metal filter (the correct name I cannot remember) behind the upper intake. My question is...Can I do anything else to the top end of the motor to help get rid of pinging? Anything I can tighten? It almost sounds like my lifters are tapping. It's a 95 5.0 with 114k miles. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>94gt</b> <br /><small>Member # 3060</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,11,8,17,35,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> its probably detonation from carbon build up... mine does the same thing with the timing @12, but its fine at 8*<br /><br /><a href="http://www.californiafords.com/ubb/ultimatebb.php?ubb=get_topic;f=6;t=006179" target="_blank">look at this link here</a> <br /><br /> <a href="http://www.californiafords.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=6;t=006054" target="_blank">and here for a little more info on the computers in the cars</a> <br /><br />Ive recently saw some1 say there are 2 "versions" of the 94-95 computer... The guy siad that there was a "high altitude" and a "low altitude" version, mainly based off of the calibration code<br />it starts with "F4VF" or something to that effect!<br /><br />I hope this helps! <img border="0" alt="[patriot]" title="" src="graemlins/patriot.gif" /> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>st5150</b> <br /><small>Member # 51</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,11,8,17,47,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Autolite 24's, a non dirty MAF and properly working EGR system will go a long way for part throttle pinging. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
